*1: Dust-tight conduit seal must be used when
installed in Class II and Class III environments.
*2: Installation should be in accordance with the
National Electrical Code® (ANSI/NFPA 70)
Sections 504 and 505.
*3: The conguration of Associated Nonincendive
Field Wiring Apparatus must be FM Approved.
*4: Associated Nonincendive Field Wiring
Apparatus manufacturer’s installation
drawing must be followed when installing this
equipment.
*5: No revision to drawing without prior FM
Approvals.
*6: Terminator and supply unit must be FM
Approved.
*7: If use ordinary wirings, the general purpose
equipment must have nonincendive eld wiring
terminal approved by FM Approvals.
*8: The nonincendive eld wiring circuit concept
allows interconection of nonincendive eld
wiring apparatus with associated nonincendive
eld wiring apparatus, using any of the wiring
methods permitted for unclassied locations.
*9: Installation requirements;
Vmax ≥ Voc or Vt
Imax = see note 10.
Ca ≥ Ci + Ccable
La ≥ Li + Lcable
*10: For this current controlled circuit, the parameter
(Imax) is not required and need not be aligned
with parameter (Isc or It) of the barrier or
associated nonincendive eld wiring apparatus.
